Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a lighter operation locking device that can prevent opening / closing operation of a lid capped on the top of a lighter (oil lighter, piezo lighter, flint type lighter) or ignition operation of an ignition operator.

[0002]

[Prior Art]

 Generally, in a gas lighter, a gas ejecting nozzle is operated by pushing down an ignition operator to start ejecting gas, and an ignition means is operated to generate a spark to ignite gas. Such gas lighters are roughly classified into a piezoelectric ignition type lighter (so-called piezo lighter) that uses a piezoelectric unit that strikes a piezoelectric element with a striking mechanism to generate a high voltage and that is ignited by spark discharge, and a flint is sanded. There is a file type lighter (so-called flint type lighter) that ignites with sparks at the time of rubbing, and a lid is openably and closably capped on the top of the piezo lighter, and the piezoelectric unit is opened and closed by the operation. There is a gas lighter with a lid to operate the. In addition, in the recent piezoelectric ignition type gas lighter, an internal combustion mechanism such as a combustion cylinder is built in the body of the lighter, and air and gas are mixed in the body of the lighter to perform burner-shaped ignition and combustion. A so-called internal combustion gas lighter, a wind resistant gas lighter, has already been devised.

Among these gas lighters, in particular, the above-mentioned piezoelectric ignition type gas lighter, the valve of the gas ejection nozzle is automatically opened by the pushing operation of the ignition operator and instantaneously. Since a spark discharge is generated and ignition occurs, it is expected that children and others will operate in a mischievous manner, and it is feared that it may cause an accident such as fire or burns. In order to do so, various operation lock devices for gas lighters have been devised, which also have stoppers that can arbitrarily block the ignition operation of the lighters.

Conventionally, as an operation lock device for such a lighter, for example, as shown in FIG. 8, an ignition operator 5 whose tip is engaged with the tip of a gas ejection nozzle 6a protruding to the top of the gas lighter main body 2 is shown. In a flint type gas lighter that ejects gas from the gas ejection nozzle 6a by pressing the valve in the valve opening direction, the flint type gas lighter is rotatably supported at a lower portion of the ignition operator 5 with respect to the ignition operator 5. At a certain position, it abuts on the upper edge of the lighter main body 2 to prevent the ignition operator 5 from descending, and at other positions, the abutment with the upper edge of the lighter main body 2 is released to perform the ignition operation. A slider piece (operation piece) 8 that is fitted into the fitting groove 4d that allows the child 5 to descend, and a slider piece 8 that is hung below the ignition operator element 5 and is rotatably inserted. Mounting shaft and below There has been a lighter with a lock member that is also fitted with a stopper S that is loosely fitted to prevent the slider piece 8 from slipping off (see Japanese Utility Model Laid-Open No. 54-44176).

Further, as shown in FIG. 9, an outer case 1 that removably accommodates the lighter main body 2, a lid 5A that is openably and closably capped on the top of the case 1, and a desired lid 5A. The collar body 5B protruding in the position, the locking ring 5C that detachably locks the outer case 1 and the collar body 5B, and the engagement between the lid body 5A and the outer case 1 are released. There is a safety device for an internal combustion type gas lighter that includes an operation button 5D (see Japanese Utility Model Publication No. 2-54048).

[0006]

[Problems to be solved by the device]

 However, among the above-described conventional operation lock devices, in the gas lighter with a lock member disclosed in Japanese Utility Model Publication No. 54-44176, the play of the stopper S (more specifically, the slider piece 8) as a lock member is prevented. Since the end side projects outward from the surface of the lighter main body 2, for example, when such a lighter is put in a pocket, bag, or the like, an external impact or a series of movements may occur. There is a drawback that the fingertip that is casually inserted inside touches the protruding portion of the stopper S (more specifically, the slider piece 8) and easily rotates in the removing direction, which is unintentionally locked. There was a problem that was removed.

[0007] Furthermore, such a stopper S has a ring-shaped mounting portion of the slider piece 8 inserted into a mounting shaft that is vertically provided under the ignition operator 5, and the stopper S is pulled out by a spring. Since it is rotatably assembled by being stopped, even if the slider piece 8 of the stopper S is moved to the locked position, it will move with an extremely slight force applied in the releasing direction (horizontal direction). In addition, it has a drawback that it rotates more than necessary (180 degrees or more).

In addition, the fitting groove 4d for locking the stopper is exposed to the outside, and the engaging state of the stopper S (specifically, the slider piece 8) can be sensed from the outside, which is aesthetic of the lighter. The appearance of the gas lighter was impaired, and the product value was lowered especially in high-end gas lighters.

On the other hand, in the safety device disclosed in the above-mentioned Japanese Utility Model Laid-Open No. 2-54048, the collar body 5B and the operation button 5D are unavoidably structurally attached to the lid body 5A or the case 1. It has a drawback that the lighter is largely projected on the surface, so that unevenness appears on the outer peripheral surface of the lighter, and it becomes bulky when put in a pocket or the like. Moreover, in such a safety device, the locking ring 5C for locking the collar body 5B and the case 1 must be fixed so that the lid body 5A does not open unexpectedly. In addition, there is a trouble that the hooking operation of the locking ring 5C must be repeated each time the lid 5A is opened and closed.

Further, in such an internal combustion type gas lighter, the mixed gas produced by the jet jet is burned and ignites in a burner shape, so that there is an advantage that it can be used without problems even under strong winds. Like a lighter, the flame does not bulge outwardly from the flame outlet at the top of the windshield and is ignited and burned in the lighter body, so the lighter member near the combustion tube is heated to some extent. In particular, in the case of the ignition operator 5, which is in direct contact with the fingers of the hand, it is desirable to keep the ignition operator 5 away from the combustion cylinder or the lighter body 2 at least during ignition.

The present invention has been made in view of the above conventional problems, and it is locked easily and surely without damaging the appearance of the lighter, and is not easily operated even if it is touched with a finger or the like. In other words, it is an object of the present invention to provide an operation lock device for a gas lighter, which can surely prevent the easy unlocking of the stopper against the intention.

[0012]

[Means for Solving the Problems]

 In order to solve the above-mentioned conventional problems and achieve the intended purpose, the structure which is the gist of the present invention is an ignition operator which is rotatably or rotatably mounted on a lighter body. In an operation lock device for a lighter, which comprises an ignition mechanism that is interlocked with an operation and a stopper that prevents the operation of the ignition operator, when the stopper is displaced to one position, one end side of the ignition locks the ignition. An operation lock device for a lighter that is reciprocally mounted in the lighter body or its outer case so as to abut against the inside of the operator and prevent the operation of the ignition operator. A lid body that is openably and closably attached to the top, an ignition operator that is rotatably attached to the lighter body, and an ignition mechanism that is interlocked with the operation of the ignition operator. In a lighter operation lock device comprising a lid or a stopper for blocking operation of the ignition operator, the stopper has one end abutting inside the lid when displaced to one position. The lighter operation lock device is reciprocally mounted in the lighter body or its outer case so as to prevent the lid body from being opened and closed.

Further, the stopper is assembled in the outer case with a slider piece that is internally installed through a slit in the outer case so that at least a part of the stopper hangs on a finger on substantially the same surface as the surface of the outer case. And a mounting member for slidably holding the slider piece, and at least one recess is provided at a desired position of the slider piece, and a surface of the mounting member corresponding to the recess is provided. It is better to form protrusions.

Further, the mounting member has a sliding surface formed at least on the upper end side through a step for aligning the slider piece, and the slider piece abutting the sliding surface. Is inserted from the inside of the outer case so as to be loosely fitted in the slit, and the mounting member is held in the outer case by pressure contact with the lighter body fitted in the outer case. preferable.

[0015]

[Action]

 In the lighter operation lock device of the present invention having such a structure, when the stopper is displaced to one position, one end of the stopper comes into contact with the ignition operator or the lid to ignite the ignition operator. Since the slider is reciprocally mounted in the lighter body or its outer case so as to prevent the operation or the opening / closing operation of the lid, the appearance of the slider piece is not sensed from the appearance of the lighter. Since it is operated by, it does not spoil the appearance of the lighter.

[0016] Further, the stopper is assembled in the outer case with a slider piece that is internally mounted through a slit in the outer case so that at least a part of the stopper hangs on a finger on substantially the same surface as the surface of the outer case. A mounting member for slidably holding the slider piece, and at least one recess is provided at a desired position of the slider piece, and the mounting member corresponding to the recess is provided. If a protrusion is formed on the surface, everything except the part of the slider piece is exposed without being exposed on the surface of the lighter, and the mounting step between the outer case and the slider piece is almost exposed on the surface. Therefore, the slider piece is not easily caught by a finger or the like, and the slider piece once slid in the locking direction has the protrusion and the concave portion. Unless the slider piece is slid in the releasing direction with a finger against the pressure contact force (friction force) with the lighter, the lighter cannot be ignited.

Further, the mounting member has a slide surface formed at least on the upper end side through a step for aligning the slider piece, and the slider piece contacted with the slide surface. Is inserted from the inside of the outer case so as to be loosely fitted into the slit, and the mounting member is held in the outer case by pressure contact with the lighter body fitted in the outer case. The operation lock device for the lighter can be easily assembled without using screws or the like.

The rotating levers 5a, 5a are provided with pivotal holes 5a formed on the free end side. ₁ , 5a₁ Is formed in the pair of support frames 3a, 3a in alignment with the pivot holes 4d, 4d of the intermediate case 4.₁ , 3a₁ When the ignition operator 5 is pushed into and rotated by the rotation levers 5a, 5a, the first projection 7d of the gate frame 7d is rotated.₁ , 7d₁ Depressing pieces 5b, 5b for engaging with and depressing the operating portion (inner box 7b) of the piezoelectric unit 7 are provided in series. Further, as shown in FIG. 5 or FIG. 6, the inner surface of the ignition operator 5, which also serves as a lid, is provided with a lower opening into which a stopper S (specifically, a slider piece 8) described later is removably engaged. The engagement groove 5c is integrally formed. Side wall 5c forming this engaging groove 5c₁ Has a notch 5c in the center₂ Are formed (see FIG. 3).

On the other hand, a stopper S that constitutes an operation lock device for the ignition operator 5 is mounted inside the outer case 1. As shown in FIG. 4, the stopper S is provided with a plate-shaped slider piece 8 and a mounting member 9 for slidably holding the slider piece 8. The slider piece 8 is provided with an operation convex portion 8a bulging on the surface and an upper end engaging portion 8b having a T-shaped cross section, and the operation convex portion 8a is the surface of the outer case 1. It is slidably mounted on the outer case 1 through a slit 1a opened so as to be hung on a finger on substantially the same plane (see FIG. 1 or 6). Further, on the back surface of the slider piece 8, two concave portions 8c, 8c arranged vertically are formed. On the other hand, the mounting member 9 is made of a transparent synthetic resin material whose surface is bulged in an arc shape so as to be aligned with the inner surface of the outer case 1, and has a step for assembling the slider piece 8 on the upper end side. The sliding surface 9a thus formed is provided. This sliding surface 9a has a small amount of elastic force (flexible force) that presses the slider piece 8 outward, and its upper end is separated by a notch groove 9a ₁ at the center. The pair of holding pieces 9a ₂ and 9a ₂ thus formed and a hemispherical surface-shaped projection 9a ₃ which is provided at a substantially central portion of the surface of the sliding surface 9a are integrally formed. The projection 9a ₃ is arranged so as to be pressed into engagement with the recesses 8c and 8d provided on the slider piece 8, and the sliding stroke of the slider piece 8 is determined by the engagement of both. It is something. Further, a transparent window portion 9b is provided on the lower surface of the mounting member 9 so as to allow the amount of liquefied gas in the transparent gas tank 3 to be visually confirmed through the slit 1b of the outer case 1. Has been done.

Further, the mounting member 9 only fits the transparent window portion 9b from the inside of the outer case 1 into the slit 1b in a state where the slider piece 8 is in contact with the sliding surface 9a. The lighter main body 2 is then inserted into the outer case 1 so that the mounting member 9 is fixed to the outer case 1 by pressure contact with the lighter main body 2 so as not to come off. Is done. Therefore, only the slider piece 8 is sandwiched on the side surface of the lighter main body 2 so as to slide on the sliding surface 9a, and as shown in FIG. In a state where the protrusion 9a ₃ having a hemispherical surface projecting on the surface 9a and the recess 8d of the slider piece 8 are engaged (sliding upper limit position), the upper end engaging portion 8b of the slider piece 8 is ignited. Since it is fitted in the engagement groove 5c of the operator 5, even if the ignition operator 5 is rotated in the lid opening direction, the side wall 5c ₁ forming the engagement groove 5c has the upper end of the slider piece 8 The lid is brought into contact with the side surface of the engaging portion 8b to prevent the lid opening operation (locked state). On the other hand, when the slider piece 8 is slid in the releasing direction (downward) with a finger against the pressure contact force (friction force) between the protrusion 9a ₃ and the recess 8d, as shown in FIG. The projection 9a ₃ engages with the recess 8c and stops (sliding lower limit position), and in this state, the upper end engaging portion 8b of the slider piece 8 is displaced so as to be disengaged from the engaging groove 5c of the ignition operator 5. Thus, the opening operation of the ignition operator 5 is enabled (unlocked state).

In the operation lock device of the gas lighter of the present invention having the above-described structure, normally (when not in use), the slider piece 8 (more specifically, the upper end engaging portion 8b) of the stopper S is ignited as described above. The hand holding the lighter body 2 is locked in the engagement groove 5c of the child 5 and is held in a locked state that prevents the turning operation of the ignition operator 5 (see FIG. 1). When the slider 8 is slid downward using the thumb of the slider against the pressure contact force (friction force) between the protrusion 9a ₃ and the recess 8d, as shown in FIG. The upper end engaging portion 8b of 8 is disengaged from the engaging groove 5c to bring the ignition operator 5 into a rotatable state (unlocked state), and then the ignition operator 5 is pushed in as it is and rotated to maintain the conventional operation. The ignition operation, that is, the pressing piece 5b of the ignition operator 5 The first protrusion 7d of Kimon type frame 7d _1, together with 7d ₁ and engaged in operating depressing the operation portion of the piezoelectric unit 7, the second protrusion 7d _2, 7d ₂ valve operation該門type frame 7d After one end of the lever 10 is engaged to push in and the gas ejection nozzle 6a is lifted and gas is ejected, the piezoelectric unit 7 is further pushed in to operate the striking mechanism to generate a high voltage. As a result, the jet gas is ignited by the spark discharge from the discharge terminal 6d (see FIG. 6).

On the other hand, after ignition, by simply releasing the thumb pushing the ignition operator 5, the return force of the piezoelectric unit 7 (specifically, the inner box 7b) automatically rotates to the closed state. Then, when the slider piece 8 is slid in the locking direction (upward) with a finger, the projection 9a3 engages with the recess 8d and stops, and the slider piece 8 moves as shown in FIG. 5 (A). The upper end engaging portion 8b is projectingly fitted into the engaging groove 5c of the ignition operator 5 to hold the ignition operator 5 in the rotation preventing state (lock state) (see FIG. 1). Further, in this locked state, all parts except the slider piece 8 are installed without appearing on the appearance of the lighter, and moreover, there is the operation convex portion 8a of the slider 8 appearing on the outside. Since it is projected so that it can be hung on a finger on substantially the same plane as the surface of the ignition operator 5, it does not easily rotate even if it is touched by a finger, etc., and it also impairs the appearance by mischief. Nor.

The operation lock device of the lighter of the present invention is not limited to this embodiment, and can be freely modified in design within the scope of the present invention, and the present invention includes all of them. To do. For example, in the present embodiment, the stopper S is assembled so as to prevent the opening / closing operation of the ignition operator 5 which also serves as the lid, but the present invention is not limited to this, and the lighter main body 2 alone can be used. The stopper S may be installed to prevent the opening / closing operation of the lid body which is openably / closably attached to the top portion and the pushing operation of the ignition operator mounted so as to be pushed vertically. As an assembling means of the stopper S for preventing the opening / closing operation of the lid body, for example, as shown in FIG.₁ And the concave portion 51c₁ A projection 8b projecting from the inner surface of the slider piece 8 at the upper limit sliding position. ₁ May be engaged. Further, although the present embodiment refers to a piezo writer, it goes without saying that it can be applied to an oil lighter and a flint type lighter.

[0029]

[Effect of the device]

 The present invention is configured as described above, and when the stopper is displaced to one position, one end of the stopper comes into contact with the ignition operator or the lid body to perform an ignition operation of the ignition operator or the lid body. Since the lighter body or the outer case is reciprocally mounted so as to prevent the opening / closing operation, the slider lighter can be operated without being noticed from the appearance of the lighter. As a result, it was possible to provide a lighter operation lock device that allows the stopper to be attached while still maintaining the original design of the lighter without damaging the appearance of the lighter.

Further, the stopper is assembled in the outer case with a slider piece that is internally installed through a slit in the outer case so that at least a part of the stopper hangs on a finger on substantially the same surface as the surface of the outer case. A mounting member for slidably holding the slider piece, and at least one recess is provided at a desired position of the slider piece, and the mounting member corresponding to the recess is provided. If a protrusion is formed on the surface, everything except the part of the slider piece is exposed without being exposed on the surface of the lighter, and the mounting step between the outer case and the slider piece is almost exposed on the surface. Therefore, the slider piece is not easily caught by a finger or the like, and the slider piece once slid in the locking direction has the protrusion and the concave portion. Unless the slider piece is slid in the releasing direction with a finger against the pressure contact force (friction force) with the lighter, the lighter cannot be ignited, so the unintended and easy ignition operation is reliably prevented. Such an effect is achieved.

Further, the attachment member has a slide surface formed at least on the upper end side through a step to align the slider piece, and the slider piece contacted with the slide surface. Is inserted from the inside of the outer case so as to be loosely fitted in the slit, and the mounting member is held in the outer case by pressure contact with the lighter body fitted in the outer case. Since the operation lock device of the lighter can be easily assembled without using screws, etc., the components are sequentially assembled into the outer case from the top, which requires a lot of work in the past. This has the effect of significantly simplifying the work.

The operation lock device of the lighter of the present invention has a simple structure, is suitable for mass production, and can be supplied to users as a low price. But there is a big thing.
